sorry that it took so long for me to reply..
I haven't been watching the board too much lately.
basically, add a timer to your form. Then, add datasubscribers for all of the variables that you want to record.
you will then need to write a sub that opens or creates a file and then another sub that writes your data as a stream into a csv file.
I'd give you a code snipet, but I'm at home now and all of that is on my work computer.
If you shoot me an email through the board, I'll respond in more detail.
